Правда немного с запазданием (вышла 11.04.2010), но все же...
Qwt 5.2.1 has been released.
Qwt 5.2.1 is a maintenance release with a couple bug fixes. It should be binary
compatible with Qwt 5.2.0 on most platforms, but I'm not 100% sure about
Windows because some pointless declarations for exporting templates have been
removed from the headers.
In opposite to earlier releases I have also uploaded the documentation as .qch file, that can be loaded into the assistant.
Qwt 5.2.1 is available from the Qwt project page:

Что действительно радует, так это наличие документации в формате *.qch, что немного упрощает жизнь...
